This is a continuation of application Ser. No. 06/920,652 filed Oct. 20, 1986. now abandoned
The present invention relates generally to knockdown shelters of the temporary type which have canopies and may be set up in a rapid manner for protection from the elements.
In common use today are temporary shelters such as those used at camp sites, fairs, flea markets and promotional shows of various types which shelters include canopies to protect the users and merchandise from the elements. Such shelters are quite costly for the reason they include a large array of tubular components which must be supported in place as by lines or alternatively embedded into the ground. Further, the large number of cross members add to the cost of the shelter as well as added effort in setting up and taking down the shelter. Further, known temporary shelters do not derive any reinforcing feature from the canvas or plastic canopy cover used therewith. A further drawback to known temporary shelters is the difficulty with which same are assembled which is complicated by the multitude of parts which must be assembled and thereafter separated at completion of shelter use.
The present invention is embodied within a temporary shelter having telescopic pole and arch assemblies with a pliable cover or canopy snugly overlying and attached to the arch assemblies.
The shelter includes a tubular framework having pole assemblies at each corner which include upwardly extensible members each for inserted engagement with an arch assembly. The pole assemblies are flattened and curved at their lower ends to facilitate supported engagement with a ground surface. The main member of each pole assembly is of a length to substantially receive the upwardly extensible member of the pole assembly. Similarly each main member of the arch assemblies carries an upwardly extensible member which may be retracted into the main member to facilitate both storage and transport of the arch assemblies within a portable container. A connector is of spider configuration and into which are inserted the upper ends of the arch assembly members.
The pliable cover includes attachment means securing the cover to the frame in a secure manner whereby the cover will enhance the rigidity of the shelter. Such attachment means may include hook and loop fabric closure pieces. The telescopic pole and arch assemblies preferably include push button latching means to permit rapid shelter erection without tools.
Important objectives of the present shelter include the provision of a shelter with telescopic pole and arch assemblies permitting retraction of pole and arch members substantially into a main member of each assembly to greatly reduce the size of the container needed for storage or carrying of the disassembled shelter; the provision of a shelter having a pliable cover which fits in a snug manner over arch assemblies to contribute to shelter rigidity; the provision of a shelter utilizing cover attachment means permitting the user to attach the cover to the framework in a secure manner without the aid of tools; the provision of a shelter which in its knockdown form may be contained within a small, lightweight case or bag to render same highly portable; the provision of a shelter including a frame of tubular construction which tubing is of polygonal section significantly contributing to shelter rigidity.
In the accompanying drawing:
FIG. 1 is a perspective view of the present shelter;
FIG. 2 is a vertical sectional view taken along line 2--2 of FIG. 1 and with the cover removed;
FIG. 3 is an elevational view taken along line 3--3 of FIG. 1 showing a framed end segment of a pole assembly;
FIG. 4 is a plan view taken downwardly along line 4--4 of FIG. 2,
FIG. 5 is a vertical sectional view taken along line 5--5 of FIG. 1;
FIG. 6 is an enlarged view of that portion of FIG. 2 encircled at 6; and
FIG. 7 is a composite view of the frame of the present shelter disassembled for stowage within a container.
With continuing attention to the drawings wherein applied reference numerals indicate parts similarly hereinafter identified, the reference numeral 1 indicates generally the present shelter in place on a natural or artificial ground surface GS with each pole assembly generally at 2 having a main member 3 and an upwardly extensible member 4. The lowermost end segment of each main member is (as best shown in FIG. 3) flattened at 5, curved at 6, to provide a foot 7. Foot 7 is apertured at 9 to receive a ground insertable spike 8.
Arch assemblies as typically shown in FIG. 2, include a main member 11 and an upwardly extensible member 12 which, as is the case with the pole assemblies, are preferably of square or otherwise polygonal in section tubing.
The extensible members 4 and 12 of the pole and arch assemblies may be retracted for stowage purposes within the main member of each assembly as shown in FIG. 7. Such retraction permits a relatively small container to be used for stowage and transport of the shelter. The linear length of the straight portions of main members 4 and 11 is approximately equal to the length of their respective extensible members 4 and 12. A vertical segment 11A of member 11 receives the upper end of pole assembly member 4.
At the apex of the shelter frame is a connector 14 having downwardly inclined arms 15 arranged in spider configuration for coupling to the uppermost member 12 of each arch assembly. The arms 15 serve to interconnect the arch assemblies and to angularly space same a desired number of degrees such as the ninety degree spacing shown in FIG. 4.
Latch means typically shown at 16 in FIG. 6 includes a leaf spring having a push button 17 thereon which projects through registerable openings in the main and the extensible members of the pole assemblies to maintain the main and extensible members thereof in extended relationship with one another. Similar latch means at 18 serves to lock the ends of arch assembly members 11 and 12 to one another. Like latch means at 19 serves to lock the upper ends of pole assembly members 4 to arch main members 11. Latch means at 20 lock the arch members 12 in inserted engagement with connector 14.
As shown in FIG. 5, a canopy at 21 is secured to the frame by canopy attachment means including a reinforcing strip 22 attached to the canopy as by stitching 23 (or other suitable means) adjacent the canopy lower edge at 21A. Strip 22 is provided with hook closure pieces 24 and 25 disposed on opposite ends of the strip 22 so as to be manually engageable with loop closure pieces 26 and 27 adhesively in place on sides of arch member 11. Accordingly, the canopy may be conveniently secured in a snug manner. Additionally, the canopy is sized so that when it is applied to the assembled frame it exerts inwardly directed forces on the frame to contribute to frame rigidity. While the hook and loop pieces provide the preferred closure means on strip 22, it is to be understood that other closure means could be utilized, such as buttons, snaps, ties, etc.
As shown in FIG. 7, the frame by reason of its telescopic pole and arch assemblies is of few components the assembly of which is self-evident to the user. The few lightweight components lend themselves to convenient transport within a hand carried case or bag. A popular use for such knockdown shelters is at flea markets whereat secondhand and hand crafted merchandise is sold.
While I have shown but one embodiment of the invention, it will be apparent to those skilled in the art that the invention may be embodied still otherwise without departing from the spirit and scope of the invention.
